It can be fixed, I gave the link some time ago,
  http://linuxtv.org/pipermail/vdr/2008-July/017347.html

Better would be to let the chip handle it,
There are so many frame rates and formats these days,
having solutions and modelines for the X server for each one
would be problematic,
Running mplayer or xine in X and having it doing resizing deinterlacing
perhaps and aspect correction just to name a few things, but then playing
50 Hz movies on a 60 Hz system does NOT make a real media player.
Maybe people got used to it, just like they got used
to low bitrate mp3, and highly compressed video....
Technology moving backwards.
